Stainless Steel Welding Wire: ER308, ER308L, ER308LSi Selection Guide

Stainless Steel Welding Wire: ER308, ER308L, ER308LSi  and how to choose them?

The key distinctions are defined by two elements:

Element Impact:

The "Si" (High Silicon): Enhances weld pool fluidity, arc stability, and bead wetting, improving operability and appearance.

How to Choose the Right Stainless Steel Welding Wire?

Post-weld heat treatment is not possible.

Application is non-corrosive, and higher ambient temperature strength is a specific, calculated requirement.

Seeking superior bead profile and wetting.

Specific procedure specifications limit silicon content.

For most MIG applications, ER308LSi offers the best balance. For critical TIG work, ER308L is standard. Always choose an 'L' grade for corrosion resistance unless post-weld heat treatment is guaranteed.
